Signal lights around the track
|
|
==============================
|
|
It is possible to use tracklights in tracks.
|
|
Currently, five types of lights are supported (all starting lights):
|
|
* red start lights
|
|
* green start lights A
|
|
* green start lights B
|
|
* yellow start lights
|
|
|
|
All these lights can have an index. I will explain the meaning of these for
|
|
every type of light. But first I will give a general example and explain every
|
|
option in it:
|
|
|
|
Example
|
|
=======
|
|
This example comes from the dirt-3 track.

|
section "Track Lights": main section
|
|
section "1": first lights (lights must be numbered from 1 to the number of
|
|
lights)
|
|
attstr "role": the role of the light (see below)
|
|
attnum "index": the index of the light (see below)
|
|
section "topleft": coordinates of the top-left corner of the light. See remark
|
|
about coordinates elsewise in this documentation.
|
|
section "bottomright": coordinates of the bottom-right corner of the light. See remark
|
|
about coordinates elsewise in this documentation.
|
|
attstr "texture on": texture of the light turned on
|
|
attstr "texture off": texture of the light turned off
|
|
attnum "red", "gree", "blue": color of the filter to put before the texture.
|
|
|
|
Coordinate remark
|
|
=================
|
|
The coordinates can be aquaried from a 3d-editing program. I know an example
|
|
where (525,21,-185) was the coordinate in the 3d-program, but (525,185,21) was
|
|
the coordinate that was good for the track xml-file. This can be seen by
|
|
looking to the axel where the gravity works on: this is the z-axel inside the
|
|
game.
